“…But there are many factors that influence the performance of laminated armature, such as the armature thickness, material and layers, the length of the tail. The contact pressure between the armature and rail is the most important factor which influences rail gun's emission efficiency and the physical phenomena of the rail's abrasion and ablation when launch [1][2][3][4]. In the initial stage, with the small given pressure and big contact stress between armature and rail, initial pre-tightening force mechanism can be reduced to decrease the armature load and enhance emission efficiency and speed.…”

Mechanics analysis model of laminated solid armature is established by finite element in this article. The orthogonal method is applied in simulation experiment of laminated armature. The contact pressure between armature and rail is studied based on parameters of armature's thickness, material ,layers, and length of the tail. Using range analysis method, contained by orthogonal analysis, the order of the factors which affecting the interface stress is the thickness of the outermost armature, the length of the tail, and armature materials. Through the analysis method of variance, the thickness of the laminated armature does the highest performance of the three factors. At last the analysis result is correct by the proof test.
